Liposomal bupivacaine nerve block for rotator cuff surgery
This study tests whether a long-lasting numbing medicine called liposomal bupivacaine (Exparel) works better than standard pain relief for people having rotator cuff surgery. It aims to lessen pain after surgery so you may need fewer pain pills.
Camden, New JerseyAges 18 years+ - NCT06133933Enrolling by invitation
Shoulder replacement and pain medication study
This study looks at how your pain tolerance before a total shoulder replacement might relate to how much pain medication you need after surgery. The goal is to help doctors better manage pain medication after surgery.

New Brunswick, New JerseyAges 18 years+ - NCT06068907Enrolling by invitation
Elbow Pain: Sensitivity to Pressure
This study is looking at how people with long-lasting elbow pain (at least 3 months) feel pressure. It aims to understand pain better for future treatments.
Istanbul, BakırkoyAges 18–65 - NCT06063902Enrolling by invitation
Long-term opioid therapy for chronic pain
This study looks at the risks and benefits of long-term use of opioids (strong painkillers) for chronic pain that is not caused by cancer. It aims to help doctors and patients make better decisions about pain management.
UppsalaAges 18 years+ - NCT06054802Enrolling by invitation
Sleep and pain after spine surgery in teens
This study looks at how sleep quality before and after spine surgery affects pain recovery. It uses text messages to check in with participants, so a mobile device is needed.
Columbus, OhioAges 10–18 - NCT06019793Enrolling by invitation
Recording brain signals during deep brain stimulation for pain
This study tests whether recording brain activity during deep brain stimulation (DBS) for chronic pain can help improve future treatments. It is for people with long-lasting, severe pain that hasn't been helped by other treatments.
Phoenix, ArizonaAges 22 years+ - NCT06006624Enrolling by invitationPhase 4
Exparel vs nerve block for ACL reconstruction pain
This trial compares two methods of pain control after ACL surgery: a long-lasting local anesthetic (Exparel) versus a nerve block. It aims to find which provides better pain relief and recovery.
Philadelphia, PennsylvaniaAges 18 years+ - NCT05964868Enrolling by invitationPhase 3
Liposome anesthesia to reduce pain after nose surgery
This Phase 3 study tests whether a special form of local numbing medicine (liposomal bupivacaine) helps reduce pain after septorhinoplasty (nose and septum surgery). You may be considered if you’re planning this surgery and can follow study instructions before and after.
Hershey, PennsylvaniaAges 18–99 - NCT05961501Enrolling by invitationPhase 2/Phase 3
CBD and CBN for long-lasting facial pain and muscle headaches
This trial tests whether CBD and CBN can reduce facial pain and headaches caused by muscle-related problems that have lasted more than 3 months. It may help people who have ongoing symptoms find a new treatment option.
WroclawAges 18 years+ - NCT05944354Enrolling by invitation
Wearable system to study spine health for military readiness
This study tests whether a wearable setup can measure spine health during training and daily movement. It may help improve how military members with or without neck or low back pain are monitored and supported.
Luke Air Force Base, ArizonaAges 18–64 - NCT05941559Enrolling by invitation
EMDR therapy for long-term rheumatoid arthritis pain
This trial tests whether eye-movement therapy (EMDR) can reduce long-lasting pain in people with rheumatoid arthritis (RA). You may be eligible if your RA has been relatively stable, your pain is still high, and you can take part in therapy sessions safely.
Enschede, OverijsselAges 18 years+ - NCT05902026Enrolling by invitation
Questionnaire study for jaw-related headache and pain impact
This study tests a biopsychosocial questionnaire (a survey about thoughts, daily life, and pain) for people with jaw-related headaches from temporomandibular disorder (TMD). It may help researchers better understand what influences headache severity and how to support treatment planning.
Gaziantep, Hasan Kalyoncu UniversityAges 18–60 - NCT05876390Enrolling by invitation
Regional anesthesia to reduce long-term breast surgery pain
This trial studies whether a pain-control technique called regional anesthesia during certain breast surgeries can lower chronic (long-lasting) pain after surgery. It may help improve comfort and quality of life for people at risk of ongoing pain after their breast operation.
Milan, LombardyAges 18 years+ - NCT05809648Enrolling by invitation
Testing a special scan to better diagnose heart blood-flow problems
This study checks whether a magnet-based heart scan (magnetocardiography) can more accurately find “true ischemia,” which means reduced blood flow to the heart, in people who come to the emergency room with chest pain. It aims to help doctors tell which chest pain is truly from heart blood-flow problems.
Rochester, MinnesotaAges 18 years+ - NCT05794373Enrolling by invitation
